What two numbers multiply to 900 and add up to 65?

Here we answer the question: "What two numbers multiply to 900 and add up to 65?"

The answer to your question is:

20 and 45

Below we illustrate and prove that 20 and 45 multiply to 900 and add up to 65:

20 × 45 = 900
20 + 45 = 65

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 65x + 900 = 0

If so, the solution to factor the quadratic equation above is:

(x + 20 ) (x + 45)

To summarize, since 20 and 45 multiply to 900 and add up 65, you know that the following is true:

x² + 65x + 900 = (x + 20 ) (x + 45)
